I have tried the "acpi=force" fix but it did not work for me. I just built a new system with: AMD Phenom X4 MSI mobo 880GM-E43 -ATI Radeon HD4250 GPU onboard (more on this below) MSI nvidia GeForce 9400 GT Ubuntu 10.04.2 kernel 2.6.32-30-generic-pae
I installed 10.04.2 and had the no shutdown problem. So I tried to load the ATI driver using System > Administration > Hardware Drivers to see if that would help. Driver install failed the first time tried with a non-specific error. I tried again and the driver installed successfully. On re-boot the display was bad (see attached) so I went back to the stock Ubuntu driver. However, I did not get a boot splash screen. So I installed the MSI nvidia GeForce 9400 GT card I had and loaded he nvidia driver using System > Administration > Hardware Drivers. Splash screen now seen. Still had the no shutdown problem. So, doesn't seem to be video driver related as I had the problem with both stock and proprietary drivers. Checked MSI for updated BIOS but I am very current with only 1 new rev available. It seems to be a very minor bug fix and would have nothing to do with my shutdown problem. If I press Esc after selecting shutdown I see the text of what is happing during the shutdown process. The text seems normal and even gives a "shutdown" command at the end and then just hangs there. I must press the power button to shutdown the system. Attached: uname -a, lspci and display screen shot with ATI driver. ** Attachment added: "lspci info" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/576204/+attachment/1923599/+files/lspci-info.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/576204 Title: lucid doesn't shut down completely -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
